Detailed Description

Uniform (quasi)-random number generator class.

Minimal random number generator of Park and Miller combinmed with a Marsaglia shift sequence. (see Numerical Recipies in Fortran 90: The Art of Parallel Scientific Computing, Chapter B7)

Member Function Documentation

gaussDeviate()

double Random::gaussDeviate

(

double

stdDeviation

)

returns a gaussian distributed deviate with zero mean and a standard deviation of stdDeviation the returned value is in the range +/- infinity (better: smallest, largest double number)

Method generates a gaussian distributed deviate with mean = 0 and the specified standard deviation borrowed from "Numerical Recipes in C++" by W.H. Press et al., Cambridge University Press

rnd()

float Random::rnd

(

)

Produces a random number between zero and one.

uniformRandInRange()

float Random::uniformRandInRange ( float  a, float  b  )

inline

get a uniformly distributed random number in [a,b]
